Any unlimited hotspot only SIM cards?

Had a house fire recently and won't get it back for a while, I have been using cellular data and it's been fine. I have my old iPhone and I've found with using a hotspot I can do things that I can't with data (update large apps, software updates etc) but I don't want to pay a huge premium for a data plan if I'm only using it as the hotspot. Are there such things as hotspot only data plans?

My Spanish video presentation got deleted

Ok so fun story…
My phone had not been working recently, so I decided to get a new phone… Anyway, I had a Spanish project that was due, and I was getting ready to turn it in. When I went into iMovie it kept saying, "downloading from iCloud". So, I went onto YouTube to try to find a way to fix this (bad choice on my part) , and it said to download and keep originals… That also did not work. I then saw something that said to turn off iCloud photos. I clicked this button and now all my photos+ videos (including my Spanish prez) ARE GONE! I'm freaking out. Is there anyway to get it back? It said it was stored in the iCloud when I turned it off, but it's no longer in my camera roll.

Upgrading iPhone contract early?

I've had my iPhone 7 for almost 2 years now and my contract end in early September. However, when I go on my EE it says my standard upgrade is early August. I'm going on holiday on the 20th of July and I was thinking about getting a new phone for then. How do I end my contract early and get my phone in time for the holiday. My friend was telling me something about having to call the company a lot earlier to get the new phone and I'm just not sure.
